Biological action and area of use of the new TXA2 antagonists:

The compounds of this invention are suitable for the treatment of diseases of the cardiovascular system, the stomach, the pancreases, the liver and the kidney. They have an antihypertensive and bronchodilatoric effect. They are suitable for inhibiting the activation of platelets. Consequently, the new TXA2 antagonists of formula I represent valuable pharmaceutical active ingredients. Moreover the compounds with a similar range of action as compared with corresponding TXA2 antagonists are marked by a significantly longer effectiveness and a greater stability through a higher specificity and selectivity (in the absence of partial agonism).

The new TXA2 antagonists have the properties typical for this compound family, such as, e.g., reduction of peripheral arterial, coronary and pulmonary vascular resistance, reduction of pulmonary blood pressure, reduction of systemic blood pressure without decreasing cardiac output and coronary circulation at the same time, promotion for renal circulation and circulation of other peripheral organs, increase of cerebral circulation, inhibition of platelet activation and dissolution of blood clots, inhibition of bronchial constriction, inhibition of hydrochloric acid secretion, cytoprotection of the heart, gastric and intestinal mucous membrane, of the liver, cytoprotection in the pancreas and in the kidney, as well as antiallergic properties. Therefore, the new TXA2 antagonists are suitable on principle for the treatment of stroke, prophylaxis and treatment of coronary heart diseases, for example, coronary thrombosis, for treatment of myocardial infarctions, peripheral arterial diseases, for prophylaxis and treatment of other thromboembolic diseases and of arterial sclerosis, in ischemic attacks of the central nervous system and other circulation disturbances of the brain, for treatment of hypertonia and for treatment of diseases whcih are accompanied by an increase of pulmonary vascular resistance, such as, e.g., pulmonary hypertonia and for treatment of shock and asthma. They can further be used for inhibition of labor and for treatment of toxicoses in pregnancies.

The new TXA2 antagonists further can be used to improve the organ function after transplantation, for example in kidney transplants, to prevent rejection reactions, instead of heparin or as an adjuvant in dialysis or hemofiltration and in the preservation of dried blood plasma, for example of dried platelet.

The new thromboxane antagonists have an antimetastatic effect and antiproliferative properties.

The new TXA2 antagonists can be used combined with, for example, carbacyclins, prostacyclin and its analogs, 7-oxoprostacyclins, prostaglandins and their derivatives and 6-keto-PGE₁ derivatives, with TXA₂ -synthetase inhibitors, with phosphodiesterase inhibitors, with antagonists and receptor antagonists of different platelet stimulators (e.g., ADP, thrombin, collagen, PAF, adrenaline, serotonin, fibrinogen) with calcium antagonists, with fibrinolytic agents and thrombolytic agents, e.g., t-PA, with heparin and other anticoagulants, with cyclooxygenase inhibitors, e.g., acetylsalicyclic acid, with inhibitors of lipoxygenases as well as antagonists from lipoxygenase products, with vasodilators such as, e.g., nitro-compounds, with antihypertensive agents such as, e.g., beta-blocking substances or with diuretics.

The does of the compounds is 0.1-500 mg/per day, also in several partial dosages, if they are administered to human patients. The unit dose for the pharmaceutically acceptable vehicle is 0.1-100 mg. For parenteral administration, sterile, injectable, aqueous or oily solutions are used. For oral administration, for example, tablets, coated tablets or capsules are suitable.

The invention thus also relates to the pharmaceutical agents based on compounds of the general formula I and usual auxiliary agents and vehicles.

The active ingredients according to the invention are to be used in connection with the auxiliary agents known and usual in galenicals e.g. for the production of hypotensors.

The unit dosage range for the ampoule is 0.1-100 gm; the range for the tablet is 0.1-100 mg.
